Until today I'd always used Airflo's Ridge for my running line and I've never really had any gripes with it. Over the winter I'd picked up some Varivas Airs and put it on the reel I use on my 6wt for summers. Today was the first day I've put it to use and I was really surprised at the difference it made in my casting. I mean, I still suck and nobody is gonna stop what they're doing to check out my sweet casting but the difference in distance was noticeable. Not to mention, I totally caught a steelhead, and that rarely happens.
